The CV Recorder 57B provides a radical new approach to generating modulation and voltage control signals. The implications for this module are extensive when placed in a modular synthesizer context.
Concept: Combine the ability to record and playback control voltage signal events from standard modules with the tools to shape, mix, loop and time scale these performances in a simple and repeatable manner. A brief list of possible uses for the 57B:
- Create asymmetric LFO shapes from Joysticks or ribbon controller signals
- Control panning and VCA parameters for automated mixing
- Record long analogue step sequence patterns while changing the step voltages and recording the clock simultaneously for later sync operations
- Combine and chain together random voltage patterns with sequences and LFOs on 4 channels
- Record envelope shapes and loop them while adjusting the loop start and end points.
- Perform granular synthesis type effects on CVs using short loops and sweeping the loop points through the sample under voltage control.
- Record lo-fi audio samples and shift playback frequency in real-time.
- 20Hz-20kHz Voltage controlled variable sample/playback rate with 1V per octave response
- 4 seconds of quad sampling @20kHz. Greater than 1 hour @20Hz
- Quad in/outs with 15 switch selectable channel recording configurations
- Record and playback simultaneously
- Rehearse mode for pre-recording experiments
- Chain multiple samples by recording with different loop points and sample rates.
- 3 loop modes: Forward, Reverse and Pendulum
- Panel and voltage controlled Loop start and End controls
- 3 Playback modes: One shot, Loop and Hold play
- Gate out provides short pulse at loop start
- Trigger input for triggering samples when not in loop mode
- Status Bi-LED indicates various record and playback states
- Channel LEDs indicate arming of channels for recording.
